Before a batch is released for sale, it is checked against independent third-party analysis. Here is where that sits in the way we work.
A batch arrives and goes into cold storage against its reference. It is not simply listed and sold — it is checked against independent analysis first, and only released once that step is complete. The reference that follows the batch through storage is the same one printed on your vial and recorded against your order.
We are deliberately careful about what we claim off the back of this. We do not publish unverifiable purity figures, because a headline number you cannot check is not worth much. What we can stand behind is the process: independent checks before release, and a batch reference that keeps everything traceable.
That is the honest version of quality control — not a marketing figure, but a documented step that every batch goes through before it reaches you.
